AB  - Azobenzenes (Azo) represent a class of organic compounds composed of two phenyl rings linked by an N=N double bond that exhibit photoisomerization, i.e. change in conformation upon UV or visible light illumination. Photoisomerization in Azo is of high yield and reversible, which is why these molecules can act as molecular photoswitches in various biomedical and energy conversion applications. However, a broader application of Azo, particularly in biomedicine, requires lower energy of photoisomerization that falls further into visible or even NIR range. In our study, selected azobenzenes were conjugated to the surface of bare gold nanoparticles (Au NP) to obtain functional hybrid nanosystems in which photoisomerization of Azo can occur upon excitation of surface plasmon in Au NP. To understand the nature of the process, the valence band structure of Azo-functionalized Au NP was investigated by synchrotron radiation VUV aerosol photoemission spectroscopy. The results demonstrate that the overlap between the valence bands of Azo and Au NP is significant to allow for chare transfer process between the components in the nanosystem.
